No errors at the server end, and its successfully executed all the time. yep, i tried with alerts, if i put an alert just after method call, it will executed. but the alert i place as the very first statement on callback method doesnt get executed. but this happens only in some occasions. worked fine in several times. pass/fail ratio = 2/3 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4041275#...
